174463-1/7022Y-1.8-21 2Pin Female Assembly Wiring Harness Automotive Connector Car Electrical Wire Socket

Product Overview

The TE Connectivity 174463-1 is a 2-position, 1-row, unsealed receptacle housing from the 070 Series MULTILOCK I/O Connector (MLC) system. This connector is designed for wire-to-wire applications and accepts 070 series receptacle contacts. The housing is molded in natural (light brown) Polybutylene Terephthalate (PBT) resin. The nominal voltage architecture is 12 V, with a working voltage of 12 VDC. The operating temperature range is from -30°C to 105°C. The centerline pitch is 3.5 mm, and the connector dimensions are: height 15.15 mm, length 10.4 mm, width 21 mm. This connector is non-sealable and is intended for applications where environmental sealing is not required.

The 070 MULTILOCK I/O connector family includes plug housings (cap housings) and receptacle housings (plug housings) in various positions from 2 to 20 ways. The 174463-1 is the 2-position receptacle housing, which mates with a corresponding 2-position cap housing (e.g., 174460). The connector system is widely used in automotive and industrial signal and low-power applications.

Contact Systems and Wire Sizes

The receptacle housing accepts 070 series receptacle contacts in two sizes: S type for smaller wires and M type for larger wires. Based on the product specification 108-5264, the applicable receptacle contacts are:
173630: Receptacle Contact (0.2 – 0.3 mm²) S Type
173631: Receptacle Contact (0.5 – 1.25 mm²) M Type
The corresponding tab contacts (for the mating housing) are:
173633: Tab Contact (0.2 – 0.3 mm²) S Type
173645: Tab Contact (0.5 – 1.25 mm²) M Type
The maximum current carrying capacity per contact is determined by wire size and number of positions. For a single contact (not de-rated), the maximum current is: 0.2 mm² – 6 A, 0.3 mm² – 8 A, 0.5 mm² – 11 A, 0.85 mm² – 15 A, 1.25 mm² – 19 A. For a 2-position connector, a reduction coefficient of 0.75 applies (according to Figure 7 of the specification). Therefore, the acceptable current for a 2-position assembly is the specified maximum current multiplied by 0.75.
